Positioning device of object clamping game machine

Abstract

A positioning device of an object clamping game machine comprises an installation plate which extends in the height axial direction, a positioning piece which extends from the installation plate in the first horizontal axial direction, and a fixing base which is fixed to the installation plate and located below the positioning piece in the height axial direction, wherein the normal direction of the installation plate is parallel to the first horizontal axial direction perpendicular to the height axial direction. And the guide pipe penetrates through the positioning sheet and the fixed seat along the height axial direction. When the guide pipe moves up and down, the positioning piece and the fixing seat have a limiting effect on the guide pipe in the radial direction of the guide pipe, and particularly, the area surrounding the guide pipe can be greatly increased through the fixing seat, so that the action path of the guide pipe is parallel to the height axial direction; and the possibility of deviation in other directions is reduced, so that the retraction and release of the clamping jaw can be controlled more accurately.

Description

Technical Field

[0001] The utility model relates to a device applied to a clamping object game machine, in particular to a positioning device for the clamping object game machine. Background Art

[0002] See also Figure 1 The clamping claw of a general clamping game machine is arranged on a positioning mechanism and driven by a driving mechanism (not shown). The positioning mechanism 1 includes a mounting plate 11, a positioning piece 12 vertically locked on the mounting plate 11, a guide tube 13 with limit rings 131 at both ends and through the positioning piece 12, a spring (not shown) sleeved on the guide tube 13 and with both ends pressing against the positioning piece 12 and one of the limit rings 131 located below, a pressing ring 14 arranged at the top of the guide tube 13 and located above the positioning piece 12, an upper stop micro switch 15 arranged on the mounting plate 11 and located adjacent to the positioning piece 12 along the extension direction of the mounting plate 11, and a lower stop micro switch 16 arranged on the mounting plate 11 and located above the upper stop micro switch 15. The spring 151 of the upper stop micro switch 15 is clamped between the pressing ring 14 and the positioning piece 12.

[0003] The driving mechanism (not shown) is a pull rope that is wound around several pulleys by a motor. The pull rope passes through the guide tube 13 and is connected to the clamp. The driving mechanism can drive the clamp to move up and down. When the motor sends the wire to the clamp to the bottom dead center, the lower stop micro switch 16 is triggered through the linkage mechanism (not shown) to generate a prompt signal. When the motor retracts the clamp to the top dead center, the clamp pushes the guide tube 13 upward to move the pressing ring 14 upward. At this time, the reed 151 of the upper stop micro switch 15 is no longer clamped and swings upward, triggering the upper stop micro switch 15 to generate a prompt signal. The above design can control the stroke of the clamp moving up and down.

[0004] However, the positioning piece 12 has only a relatively small annular inner wall surface surrounding the guide tube 13. Therefore, the guide tube 13 is prone to radially shake and become skewed due to uneven force and instability during the process of moving up and down relative to the positioning piece 12. This can easily affect the timing of releasing the reed 151 of the upper stop microswitch 15, causing the triggering time to be advanced or delayed. Although these factors can produce special game effects, the industry still hopes to be able to artificially control these factors, that is, to reduce the degree of deviation of the guide tube 13 when it moves and improve the accuracy of the retraction and release of the clamping jaws when necessary. Utility Model Content

[0005] The utility model aims to provide a positioning device which can improve the stability and the retraction and extension accuracy of the clamping jaws when they move up and down.

[0006] The utility model discloses a positioning device for a clamping game machine, wherein the positioning device comprises a mounting plate extending along a height axis, a positioning piece extending from the mounting plate along a first horizontal axis perpendicular to the height axis, a fixing seat fixed to the mounting plate and located below the positioning piece along the height axis, and a guide tube passing through the positioning piece and the fixing seat along the height axis, wherein the normal direction of the mounting plate is parallel to the first horizontal axis.

[0007] The positioning device of the utility model comprises a fixing seat comprising a supporting plate portion resting against the bottom surface of the positioning plate and parallel to the positioning plate, a seat body portion protruding downward from the supporting plate portion, and a fixing plate portion extending upward along the height axis from one end of the supporting plate portion adjacent to the mounting plate and fixed to the mounting plate.

[0008] In the positioning device of the utility model, the seat body of the fixing seat and the fixing sheet are respectively located on the opposite sides of the mounting plate along the first horizontal axis.

[0009] The positioning device of the utility model has a maximum width of the support plate portion of the fixed seat in a second horizontal axis perpendicular to the height axis and the first horizontal axis, which is greater than the maximum width of the seat body in the second horizontal axis.

[0010] In the positioning device of the utility model, the thickness of the positioning piece in the height axis direction is smaller than the thickness of the supporting plate portion of the fixed seat in the height axis direction, and the thickness of the supporting plate portion in the height axis direction is smaller than the thickness of the seat body portion in the height axis direction.

[0011] The positioning device of the utility model further includes a lower buckle ring arranged on the guide tube and located below the positioning piece along the height axis, an upper buckle ring arranged on the guide tube and located above the positioning piece along the height axis, a clamping piece arranged on the guide tube and located between the upper buckle ring and the positioning piece along the height axis, and a spring sleeved on the guide tube and with both ends respectively pressing against the fixing seat and the lower buckle ring.

[0012] The beneficial effect of the utility model is that when the guide tube moves up and down, the positioning piece and the fixing seat produce a limiting effect on the guide tube in the radial direction of the guide tube. In particular, the fixing seat can greatly increase the area surrounding the guide tube, thereby making the movement path of the guide tube parallel to the height axis and reducing the possibility of offset in other directions. In this way, the retraction and extension of the clamping jaws can be controlled more accurately. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0019] See also Figure 2 and Figure 3 The embodiment of the positioning device 2 of the clamping game machine of the utility model comprises a mounting plate 21 arranged vertically and extending along a height axis A, a positioning piece 22 extending from the mounting plate 21 along a first horizontal axis B perpendicular to the height axis A, a fixing seat 23 fixed on the mounting plate 21 and located below the positioning piece 22 along the height axis A, a guide tube 24 passing through the positioning piece 22 and the fixing seat 23 along the height axis A, and a fixing seat 23 arranged at the mounting plate 21. A lower buckle ring 25 is disposed on the guide tube 24 and is located below the positioning piece 22 along the height axis A, an upper buckle ring 26 is disposed on the guide tube 24 and is located above the positioning piece 22 along the height axis A, a clip 27 is limited by the upper buckle ring 26 and is located on the guide tube 24 and is located between the upper buckle ring 26 and the positioning piece 22 along the height axis A, and a spring 28 is sleeved on the guide tube 24 and has its two ends respectively abutting against the fixing seat 23 and the lower buckle ring 25.

[0020] The normal direction of the mounting plate 21 is parallel to the first horizontal axis B, and is provided with a plurality of locking holes and through holes. The positioning plate 22 is integrally extended from the mounting plate 21, and is usually manufactured together with the mounting plate 21. The fixing seat 23 includes a supporting plate portion 231 that abuts against the bottom surface of the positioning plate 22 and is parallel to the positioning plate 22, a seat body portion 232 that protrudes downward from the supporting plate portion 231, and a fixing plate portion 233 that extends upward along the height axis A from one end of the supporting plate portion 231 adjacent to the mounting plate 21. The maximum width of the supporting plate portion 231 on a second horizontal axis C that is perpendicular to the height axis A and the first horizontal axis B is greater than the maximum width of the seat body portion 232 on the second horizontal axis C. The thickness of the positioning piece 22 in the height axis A is smaller than the thickness of the support plate portion 231 of the fixing seat 23 in the height axis A, and the thickness of the support plate portion 231 in the height axis A is smaller than the thickness of the seat body portion 232 in the height axis A. The seat body portion 232 and the fixing piece portion 233 are respectively located on opposite sides of the mounting plate 21 along the first horizontal axis B, and the fixing piece portion 233 is locked on the mounting plate 21 by bolts (not shown), but of course it can also be fixed by other means.

[0021] See also Figure 2 , Figure 3 ,and Figure 4 The present embodiment is matched with a driving mechanism 3, which includes a driving wheel 31 pivoted on the mounting plate 21 and driven by a motor, an upper pulley 32 spaced from the driving wheel 31 along the second horizontal axis C and pivoted on the mounting plate 21, a swinging member 33 pivoted eccentrically on the mounting plate 21 and capable of swinging relative to the mounting plate 21, a lower pulley 34 pivoted on the swinging member 33 and located relatively below the upper pulley 32 along the height axis A, a pull rope 35 with one end fixed to the driving wheel 31 and passing through the upper pulley 32 and the lower pulley 34, a down stop micro switch 36 fixed to the mounting plate 21 and adjacent to the swinging member 33 along the first horizontal axis B, and an up stop micro switch 37 fixed to the mounting plate 21 and adjacent to the positioning piece 22 along the first horizontal axis B. The pull rope 35 passes through the guide tube 24 and is connected to the clamping jaw 4 after passing through the lower pulley 34 .

[0022] See also Figure 2 , Figure 4 ,and Figure 5When the motor drives the driving wheel 31, the pull rope 35 is hoisted to increase or decrease the tension of the pull rope 35. When the clamp 4 reaches the bottom dead center, the tension is reduced, causing the swing member 33 to be driven by the return spring 331 to swing, thereby triggering the bottom stop micro switch 36. Conversely, when the clamp 4 reaches the top dead center, the clamp 4 will Figure 5 As shown, the guide tube 24 is pushed upward to compress the spring 28, so that the clip 27 moves away from the positioning piece 22 along the height axis A, so that the reed 371 of the upper stop micro switch 37 originally clamped by the clip 27 and the positioning piece 22 will be released, and the reset reed 371 will trigger the upper stop micro switch 37, thereby releasing a signal of reaching the top dead center, so as to facilitate the subsequent actions of closing the clamping jaws 4. In the process of the clamping jaws 4 pushing the guide tube 24, the positioning piece 22, the support plate portion 231, and the seat body portion 232 can provide the effect of limiting the guide tube 24, so that the guide tube 24 can move only along the height axis A as much as possible, reducing the possibility of its radial deflection and shaking.

[0023] In summary, the positioning piece 22, the supporting plate portion 231, and the seat body portion 232 can provide a further positioning effect, improve the stability of the guide tube 24 during movement and reduce the eccentric swing. At the same time, the upper stop micro switch 37 can be triggered more accurately at the upper dead point, thereby improving the accuracy of the subsequent retraction and extension of the clamp 4. When the operator wants to adjust the feel of the clamp 4, the fixing piece portion 233 can also be removed from the mounting plate 21, thereby removing the fixing seat 23. In this way, the control characteristics can be adjusted. It is highly versatile and allows the operator to control more variables, so the purpose of this utility model can be achieved.
